摘  要：
【目的】研究以有机替代为基础的施肥方式对滴灌玉米生长和磷素营养的影响,为有机无机肥配施在滴灌农田施用提供参考。【方法】设置CK(不施肥对照)、化肥、秸秆还田、精制有机肥、有机无机复合肥以及秸秆还田分别与精制有机肥和有机无机复合肥混施8个处理,通过连续2年定位试验,研究其对玉米干物质量、磷素营养和肥料利用率的影响。【结果】施用6 000 kg/hm~2精制有机肥和6 000 kg/hm~2玉米秸秆处理,分别较单施化肥的玉米植株干物质量、产量、含磷量和吸磷量分别增加了5 320 kg/hm~2、1 810 kg/hm~2、0.48 g/kg和34.6 kg/hm~2。6 000 kg/hm~2精制有机肥和6 000 kg/hm~2玉米秸秆配施化学磷肥利用率最高为67.0%,比单施化肥提高了38.5%。【结论】不同有机替代方式均能促进玉米生长,增加植株含磷量和吸磷量,提高肥料利用率。

摘  要：
【Objective】In order to offer reference for the application of organic and inorganic fertilizer under drip irrigation,the influence of maize growth and P nutrient based on different strategies of organic matter substituting chemical fertilizer was investigated.【Method】Eight treatments were set up for the two consecutive years of positioning test,which included CK,chemical fertilizer,corn stalk,organic matter,organic-inorganic compound fertilizer,and corn stalk applyed with organic matter and organic- inorganic compound fertilizer,respectively. The effects of dry matter,P nutrient and fertilizer use efficiency were studied. 【Result】Compared with chemical fertilizer,applying 6,000 kg/hm~2 organic fertilizer and 6,000 kg/hm_2 corn stalk significantly increased dry matter,yield,P content and absorption by 5,320 kg/hm2,1,810 kg /hm~2,0. 48 g/kg and 34. 6 kg/hm_2 respectively. Furthermore,chemical P use efficiency was also significantly enhanced,38. 5% higher than chemical fertilizer,and the value reached to 67. 0%.【Conclusion】In conclusion,different strategies of organic matter substituting chemical fertilizer could alternative promote maize growth,increase P content and uptake,and improve the utilization rate of fertilizer.
